3D Printer prep - ideas for plastic parts you wish they made?

Recommended Posts

Why not to print an underwater housing? Has anyone tried?

 

There are some 3D printers that use a laser to selectively sinter titanium or brass powders into a solid metal of any shape, and then let you shake off the excess powder that wasn't sintered. Those would probably be interesting for camera housings, since the sintered metal is strong and watertight.

 

The main issue is that 3D printing doesn't leave smooth surfaces, there are voxels (the 3D equivalent to pixels) around 0.1mm or .004". For many uses those voxels are OK, but that sort of rough surface tends to cause problems with o-rings and sealing-- think of lots of sand on every o-ring surface, and what that would do to seals over time.

Well, it took some dialing in but the printer is finally functional. Made my first 'real' part (by which I mean, not just a part to improve the functioning of the machine itself, like a filament guide arm, hubs for the filament spindles to hold skate bearings and improve the filament feed, flange-mount end pieces for the PVC filament spool support piping, dial plunge-gauge mounting to the print head...) today.

 

It's pretty simple - just a contoured slipcover for a Manfrotto/Gitzo tripod QR plate so you can leave the QR plate on the camera and not suffer the pains of those wedge points in the webbing between your thumb and forefinger, should you like to use your left hand to support under the body as you finger the lens zoom rings. (Out of housing, obviously.)

EDIT LOL that link above is bad, but it's so funny I left it in there. Correct link here:

I'll probably more or less retire from posting in this thread and let it fade into the memory hole, but will post new DIY threads with specific subjects as I start churning out parts to try and make photographic life easier.

The 3d printing technique is becoming more popular day by day in the personalized in gift industries with various 3d toys. The 3d printing technology is used in communication . automotive industry is making use of slm , dlm technology to get their prototypes tested for utmost safety and performance.

 

Weiry:

I'll probably use Google (now Trimble) Sketchup for the most part - because I can't afford a personal copy of Solidworks and can't use my work's software for personal use (legally).

gobidion:

Most 3D printed parts are pretty swiss cheesey (the 'infill' for the middle volumes is done as a network of hexagons or grids vs. solid, to save plastic and speed up print time) and delamination of the 3D printed 'raster layers' is an issue since the plastic is deposited molten, layer by layer, and firms up somewhat before the next layer comes around. Proper orientation of the part because of that is necessary if they're going to be under any strain in use (e.g. printing a wrench you print it 'flat' since the within-layer bond is much stronger than the between-layer bond). Unlike injection molding, I would NOT trust a plastic part made by FFF or FDM to be even remotely watertight, much less under significant external pressure!

I suppose you could 3D print a housing 'mandrel' and use it as a forming tool of sorts - insert metal posts for control penetrations and then overlay it all with fiberglass or carbon fiber for the actual pressure shell - but at that point just milling an aluminum blank to tool up on isn't going to cost much more in non-recurring expense terms.

Definitely planning to use it only for fittings of one sort or another, either entirely inside or entirely outside of the housing's seal. And for those outside, it'll probably 'bubble' a bit as air seeps out of all the little pockets (that, or implode on descent! biggrin.png )

@rtrski: It has been a while since I looked into this issue, but you may want to verify your company's Solidworks license terms. A lot of software vendors, instead of fighting the illegal copies, have moved to a model that specifically allows home use of a properly licensed work/office software. In particular, I believe that Microsoft has allowed this for their MS Office for several years.

Just curious if there are other parts out there that people wish they had or the manufacturers made, that could be 3D printed in plastic? (...)

 

Open question...any other idears?

 

Threaded filter adapter for Panasonic 7-14mm that still fits in the Nauticam 6" dome please :D

Anyone has successfully printed threaded mount for lenses? I have been trying.. But not much success with fine threads.

Couple with the fact that lenses are typically aluminum... And the pla or abs material will sooner or later cause problem

this one looks like it could be printed, though the version above has indeed a metal ring for thread....I wouldn't mind ordering from them but shipping from US + customs fees would make it rather expensive :S

Also no clue if it would fit in the 6" port....

 

Alternatively there is this one, but it does not cover the full 7-14 spectrum..

Hm.. I wouldn't buy that if it for underwater...

 

And yes I also seen mostly using an aluminum ring. Ive seen some made where they pause the print.. The drop in the threaded piece.. Then let it continue print. Works well.. But too much of a bother..

I seen some use some epoxy and glue the aluminum on to the pla/abs.. But. I still think... Over time.. It will wear out..

 

I am beginning to think the usual lens threads are too small for the printer to get it right....

I have an Aquatica 5D MII uw housing. The problem I have is the engagement of the rubber wheels that engage the dials. The rubber wheels in the housing tend to slip and/or not engage the camera controls properly. I wish there was a way to replace the rubber wheels in the uw housing with something that more firmly engages the dials and switches on the camera. This may be a combination of making a piece that goes over the camera dials (e.g. mode dial) and also replaces the uw housing rubber wheel that engages the these dials and switches. The camera dials can be tough to turn some times and the rubber wheels tend to slip/wear out over time.
